with the appliance. Cleaning and maintenance should not be performed by
children without supervision.
9 If the supply cord is damaged, it must be replaced by the manufacturer, its
service agent, or similar qualified persons in order to avoid a hazard.
10 Follow local regulations regarding disposal of the appliance due to flammable
refrigerant and gas. All refrigeration products contain refrigerants, which

Setting up your refrigerator
Before using your refrigerator
1 Remove the interior packing.
2 Let the refrigerator stand upright for approximately four hours before
connecting it to power. This reduces the possibility of a malfunction in the
cooling system from improper handling during transportation.
3 Clean the interior surface with lukewarm water using a soft cloth.
4 Wait for approximately 24 hours after the thermostat has been set before
Finding a suitable location
placing any food in your refrigerator.
• This refrigerator is designed to be free standing only.

Using a 3-prong plug and outlet
Using a grounding adapter
• Place your refrigerator on a floor that is strong enough to support the
refrigerator when it is fully loaded.
• Position the refrigerator in a location away from direct sunlight, because it
may affect the acrylic coating and heat sources may increase electrical
consumption. To ensure optimal performance, install in areas with an ambient
temperature between 41° F (5° C) and 109° F (42.8° C).
• Avoid locating the refrigerator in moist areas.
• The refrigerator door must be able to swing fully open.
Leveling your refrigerator
• It is very important for the refrigerator to be level. If the refrigerator is not
leveled during installation, the doors may not close or seal properly, causing
cooling, frost, or moisture problems.
• To level your refrigerator, rotate the leveling feet clockwise (to raise) the
refrigerator or counter-clockwise (to lower).
Note: Having someone push against the top of the refrigerator helps to take some weight
off the leveling foot, making it easier to adjust.
Providing proper ventilation
Place the refrigerator at least one inch from the wall on each side to ensure proper
airflow to the compressor. Do not place the refrigerator near any heat sources,
such as a heater or stove, as this may put a strain on the compressor.
Providing a proper power supply
Check your local power source. This refrigerator requires a 110 V-120 V, 60 Hz
power supply.
Use a receptacle that accepts the grounding prong. The power cord is equipped
with a 3-prong (grounding) plug which mates with a standard 3-prong
(grounding) wall outlet to minimize the possibility of electric shock hazard from
this refrigerator.
Notes:
• The refrigerator should always be plugged into its own individual electrical outlet
which has a voltage rating that matches the rating plate.
• Never unplug your refrigerator by pulling on the power cord. Always grip the plug
firmly and pull straight out from the outlet.

1 SET button
2 LED indicatorsLight to show the current refrigerator setting.
3 STANDBY LED
• The first time you turn the refrigerator on, the control panel LEDs turn on for
three seconds, then displays the current setting (default = 3). Your refrigerator
runs continuously for several hours until it reaches the preset temperature.
After your refrigerator is fully cooled, you can adjust the temperature up or
down to your personal preference.
• To temporarily suspend cooling in the refrigerator and freezer, press and hold
the SET button for three seconds. The STANDBY LED turns on and cooling is
turned off. Press the SET button again to cancel standby mode and resume
cooling.
Notes:
• If the refrigerator is unplugged or loses power, you must wait three to five minutes
before restarting it. If you attempt to restart before this time delay, the refrigerator will
not start.
• Large amounts of food will lower the cooling efficiency of the refrigerator.
• If you choose to change the thermostat setting, adjust it by one increment at a time.
Allow 24 hours for the temperature to stabilize between adjustments.

foods varies and the recommended storage time should not be exceeded.
Reversing the door position

Maintaining your refrigerator
Your refrigerator is designed for year-round use with only minimal cleaning and
maintenance.
When you first receive it, wipe the cabinet with a mild detergent and warm water,
then wipe dry with a dry cloth. Do this periodically to keep your refrigerator
looking new.
CAUTION:
To prevent damage to the finish, do not use:
• Gasoline, benzine, thinner, or other similar solvents.
• Abrasive cleaners.
1 Turn off the refrigerator and unplug it from the wall outlet.
2 Remove all food.
3 Wash the inside with a damp warm cloth soaked in a solution of one quart of
lukewarm water to two tablespoons of baking soda solution.
4 Be sure to keep the door gasket (seal) clean to keep the refrigerator running
efficiently.
5 Dry the interior and exterior with a soft cloth.
Defrosting the freezer
This refrigerator is frost free, so you don't need to defrost it. You just need to clean
it periodically, following the above instructions.
Changing the interior LED light
1 Using a Phillips screwdriver, remove the screw securing the lamp cover, then
remove the lamp cover.
2 Remove the LED light bulb from the lamp base, then install a new LED light
bulb.
3 Reinstall the lamp cover with the screw you previously removed.

Shutting down your refrigerator - long vacations
(several months)
1 Turn off the refrigerator and unplug it from the wall outlet.
2 Remove all food.
3 Clean the refrigerator.
4 Leave the door open slightly to avoid possible formation of condensation,
mold, or odor.
CAUTION: Use extreme caution with children. The refrigerator should not be accessible to
child's play.
Moving your refrigerator
1 Turn off the refrigerator and unplug it from the wall outlet.
2 Remove all food.
3 Securely tape down all loose items inside your refrigerator.
4 Tape the doors shut.
Be sure the refrigerator stays in the upright position during transportation.
Tips on saving energy
• Locate your refrigerator in the coolest area of the room, away from heat
producing appliances or heating ducts and out of the direct sunlight.
• Let hot foods cool before placing them in the refrigerator. Overloading the
refrigerator forces the compressor to run longer. Foods that freeze too slowly
may lose quality or spoil.
• Wrap foods properly and wipe containers dry before placing them in the
refrigerator. This cuts down on frost build-up inside the refrigerator.
• Organize and label food to reduce door openings and extended searches.
